Trace the calls to DeletePiecesService.DeletePieces method and add

is dialed and duration time spent on dialing storage nodes.
These statistics will help us to find out if we should implement

that we see that we're spending too much time dialing frequent storage
nodes.

Currently SNs report their free disk space once per hour. If a node
becomes full, it has to wait until the next contact cycle begins to
report; all the while receiving and failing upload requests. By increasing
the minimum required disk space, we can give the storage nodes more time
to report their space before the completely fill up. This change goes
hand-in-hand with another change we want to implement: trigger capacity
report on SN immediately upon falling below threshold.

this commit updates our monkit dependency to the v3 version where
it outputs in an influx style. this makes discovery much easier
as many tools are built to look at it this way.
graphite and rothko will suffer some due to no longer being a tree
based on dots. hopefully time will exist to update rothko to
index based on the new metric format.
it adds an influx output for the statreceiver so that we can
write to influxdb v1 or v2 directly.

Change is adding object deletion to BeginObject request (before upload).
Now when satellite controls deletion we can move deletion before upload
to satellite. This change improves two things:
* no need for additional request to delete object before upload (need
one more change to storj/uplink)
* fix an issue with lack of permissions to upload if caveat allows only
for writing (e.g. disallow deletes but allows to write)

Change DeleteObjectPieces for deleting the segments' pointers of an
object in a reverse order.
Last segment: L
N: total number of segments
Deleting in reverse order is: L, n-1 to 0
Deleting in reverse order makes BeginDeleteObject usable to delete
partially uploaded objects that were interrupted (e.g. upload
cancellation).
With this change, the uplink upload cancellation, can be changed to use
BeginDeleteObject to cleanup already uploaded segments without having to
retrieve orders and dial every single node which stored a piece.

This change updates the storagenode piecestore apis to expose access to
the full piece size stored on disk. Previously we only had access to
(and only kept a cache of) the content size used for all pieces. This
was inaccurate when reporting the amount of disk space used by nodes.
We now have access to the total content size, as well as the total disk
usage, of all pieces. The pieces cache also keeps a cache of the total
piece size along with the content size.

This change is a special case for batch processing. If in batch request
CommitSegment and CommitObject are one after another we can execute
these request as one. This will avoid current logic where we are saving
pointer for CommitSegment and later we are deleting this pointer and
saving it once again as under last segment path for CommitObject.

live accounting used to be a cache to store writes before they are picked up during
the tally iteration, after which the cache is cleared. This created a window in which
users could potentially exceed the storage limit. This PR refactors live accounting to
hold current estimations of space used per project. This should also reduce DB load
since we no longer need to query the satellite DB when checking space used for limiting.
The mechanism by which the new live accounting system works is as follows:
During the upload of any segment, the size of that segment is added to its respective
project total in live accounting. At the beginning of the tally iteration we record
the current values in live accounting as `initialLiveTotals`. At the end of the tally
iteration we again record the current totals in live accounting as `latestLiveTotals`.
The metainfo loop observer in tally allows us to get the project totals from what it
observed in metainfo DB which are stored in `tallyProjectTotals`. However, for any
particular segment uploaded during the metainfo loop, the observer may or may not
have seen it. Thus, we take half of the difference between `latestLiveTotals` and
`initialLiveTotals`, and add that to the total that was found during tally and set that
as the new live accounting total.
Initially, live accounting was storing the total stored amount across all nodes rather than
the segment size, which is inconsistent with how we record amounts stored in the project
accounting DB, so we have refactored live accounting to record segment size

Create a service for deleting pieces of storage nodes.
Currently the DeletePieces method returns after a success threshold,
completion or a timeout.
The end goal is to return when reaching the success threshold and
leaving the remaining goroutines running after DeletePieces method
returns and add a life cycle to the service that it waits for them when
it closes.

As per discussed we decided to rate limit how fast we iterate through

For improving the deletion performance we are shifting the
responsibility to delete the pieces of the object from Uplink to the
Satellite.
BeginDeleteObject was the first call to return the stream ID which was
used for after retrieving the list of segments and then get addressed
order limits for deleting the pieces (of each segment) from the storage
nodes.
Now we want the Satellite deletes the pieces of all the object segments
from the storage nodes hence we don't need anymore to have several
network round trips between the Uplink and the Satellite because the
Satellite can delete all of them in the initial BegingDeleteObject
request.
satellite/metainfo.ListSegments has been changed to return 0 items if
the pointer of the last segment of an object is not found because we
need to preserve the backward compatibility with Uplinks that won't be
updated to the last release and they rely on listing the segments after
calling BeginDeleteObject for retrieving the addressed order limits
to contact the storage nodes to delete the pieces.

The endpoint listSegmentsManually method misses a check for the limit
parameter, otherwise it can return inconsistent results when it's 0 or
negative.
When 0 or negative, without the check, it returns no segments but also
that there isn't more segments and that isn't correct.
The function is only called from the Endpoint.ListSegments method and
the function cares to ensure that limit is always greater than 0, but if
the method doesn't check that a new future caller could misuse it and
provoke a bug.
Additionally:
* Documentation for the modified function has been written
* The part of the function that repeated the logic of the
Endpoint.getPointer method has been removed for using that method.
* Added logging before returning an internal error in
Endpoint.getPointer.
